2. Drainage - Wikipedia

   en.wikipedia.org/wiki/Drainage

   If the water pressure is not drained appropriately, retaining walls can bow, move, and fracture, causing seams to separate. The water pressure can also erode soil particles, leading to voids behind the wall and sinkholes in the above soil. Traditional retaining wall drainage systems can include French drains, drain pipes or weep holes. To ...

3. Gabion - Wikipedia

   en.wikipedia.org/wiki/Gabion

   A gabion wall is a retaining wall made of stacked stone-filled gabions tied together with wire. Gabion walls are usually battered (angled back towards the slope), or stepped back with the slope, rather than stacked vertically. The life expectancy of gabions depends on the lifespan of the wire, not on the contents of the basket.

4. Bunding - Wikipedia

   en.wikipedia.org/wiki/Bunding

   Bunding, also called a bund wall, is a constructed retaining wall around storage "where potentially polluting substances are handled, processed or stored, for the purposes of containing any unintended escape of material from that area until such time as a remedial action can be taken."

5. Drain-waste-vent system - Wikipedia

   en.wikipedia.org/wiki/Drain-waste-vent_system

   A sewer pipe is normally at neutral air pressure compared to the surrounding atmosphere.When a column of waste water flows through a pipe, it compresses air ahead of it in the system, creating a positive pressure that must be released so it does not push back on the waste stream and downstream traps, slow drainage, and induce potential clogs.

6. Retention basin - Wikipedia

   en.wikipedia.org/wiki/Retention_basin

   Storm water is typically channeled to a retention basin through a system of street and/or parking lot storm drains, and a network of drain channels or underground pipes.. The basins are designed to allow relatively large flows of water to enter, but discharges to receiving waters are limited by outlet structures that function only during very large storm eve

8. Completion (oil and gas wells) - Wikipedia

   en.wikipedia.org/wiki/Completion_(oil_and_gas_wells)

   Screen designs are mainly wire-wrap or premium; wire-wrap screens use spiral-welded corrosion-resistant wire wrapped around a drilled basepipe to provide a consistent small helical gap (such as 0.012-inch (0.30 mm), termed 12 gauge). Premium screens use a woven metal cloth wrapped around a basepipe.

9. Watershed delineation - Wikipedia

   en.wikipedia.org/wiki/Watershed_delineation

   Watershed delineation is the process of identifying the boundary of a watershed, also referred to as a catchment, drainage basin, or river basin.It is an important step in many areas of environmental science, engineering, and management, for example to study flooding, aquatic habitat, or water pollution.
